Gainward GTX 670 Phantom’s cooler has to deal with the factory overclock but it manages to do its job well, at least when it comes to keeping thermals in check. Our test with a single GTX 670 Phantom graphics card revealed temperatures up to 79 degrees Celsius, but SLI drove the first card to 85 degrees Celsius.

When it comes to noise levels, a single GTX 670 Phantom is about the same as the reference GTX 670. Cooling performance and noise are even better after considering the high factory overclock of the Phantom, but we have indeed seen better. Unfortunately, our GTX 670 Phantom SLI ran a bit loud after some gaming. The fans weren't too loud, but they are louder two GTX 680s in SLI.

The fans are quiet in idle mode.

For overclocking we left the fans in AUTO mode, since manual settings didn’t affect overclocking that much. Thermals were good even after our overclock but the fans are really loud.
